No, I think getting H.264 or H.263+ support into iaxclient will
require some effort. The ffmpeg support in iaxclient is not well
maintained and I doubt that it currently does much of anything.

A couple years ago, some of us were working with ffmpeg and x264 with
iaxclient. We had some success with that then, but ultimately changed
our focus to theora because of patent licensing concerns surrounding
H.264.

I think that with a little love, the ffmpeg support in iaxclient could
be made to work.
